The expanding need for massive data storage and processing has driven the migration from 2D to 3D architectures for logic and memory chips. These complex architectures, with their high aspect ratio (HAR) designs and ultra-thin layers, are forcing advances in metal and oxide deposition processes. Atomic layer deposition (ALD) is usually the method of choice for producing uniform layers with precisely controlled composition.

Advanced 3D architectures for logic and memory devices increasingly rely on atomic layer deposition (ALD) to achieve high-quality, nanoscale conformal coatings. ALD deposits reactants and precursor molecules in alternating pulses to create the desired chemical makeup of the layers. Because of its ability to produce extremely thin films of uniform thickness and composition, ALD has supplanted physical vapor deposition (PVD) as the dominant deposition process for leading-edge technology nodes.

The Entegris Safe Delivery Source® (SDS®) package has been the leader in providing subatmospheric specialty gas storage and delivery for ion implant dopant materials since its inception more than twenty years ago.

The purpose of a CMP process is simple – to planarize the top layer of oxide or metal with an abrasive slurry. Manufacturing the slurry to the exacting standards required by the end user is not easy. To effectively planarize the wafer surfaces, both large and small abrasive particles must be removed prior to being dispensed. Thus, the target is a narrow particle size distribution between 30 and 200 nm to prevent both microscratches and underlayer defects.

Overview The rapid increase of semiconductors in cars enables significant safety, connectivity, mobility, and sustainability improvements. As transportation transforms from being driver controlled to software controlled, automakers must look closer at their ability to measure and maintain product reliability throughout the vehicle’s lifetime.

A high purity sub-fab serves as the central nervous system of a semiconductor cleanroom. It houses chemical delivery, purification, recycling, and destruction systems. The sub-fab is where potentially hazardous aqueous chemistries and gases are stored and handled until they are delivered to the cleanroom process equipment located either in the floor above it or the building adjacent to it.

The electric vehicle (EV) market is expanding in response to customer demand, with multiple major automotive companies offering lower cost models with longer driving range.

Migration from 2D to 3D structures for high-density memory devices changes the nature of etching and deposition processes, especially as the number of layers for 3D NAND integration grows to 96 and beyond, and new process chemistries become commonplace. The greater number of lengthy processing steps and high aspect ratio (HAR) features involved place new demands on all steps of the chip manufacturing process, including etching, deposition, and cleaning equipment. Consistent process stability becomes harder to achieve.

Much as a bolt of lightning can strike in one spot and travel, creating a path of destruction in its wake, a single electrostatic discharge can have a similar effect on a semiconductor manufacturer’s bottom line. For advanced-node manufacturers, the risk posed by electrostatic discharge has become amplified by the move to fluoropolymers, a consequence of stainless-steel process tool components failing to meet increased purity requirements.

Entegris recently wrapped up an exciting week at the first-ever SEMICON West virtual event. The event provided a great opportunity to connect with the community and gain valuable insight into the future of the industry.

Photochemicals are playing an increasingly important role in bringing next generation devices to reality. While semiconductor manufacturing has always needed a pure, contamination-free environment, the requirements are tightening even further.
